Overview

IAMMETER WEM2067 is a dual-phase Wi-Fi energy meter aimed at residential monitoring jobs that need two measurement channels in one compact DIN-rail device. It fits especially well in North American split-phase homes and in single-phase solar setups where one channel monitors the grid side and the other monitors the inverter side.

Compared with a full three-phase meter, WEM2067 is the simpler choice when the job only needs two lines measured. It keeps IAMMETER's familiar cloud and integration story while lowering complexity for home users.

Why It Stands Out

  • Built specifically for dual-phase and split-phase monitoring instead of forcing a three-phase meter into a two-channel job.
  • Supports bi-directional metering, so it can track import and export energy in solar applications.
  • Offers built-in Wi-Fi plus open integration paths through Modbus TCP, Modbus RTU, and local HTTP-based monitoring.
  • Ships as a compact 2-DIN device with two 150A split-core CTs, which keeps small residential installs straightforward.

Best Fit

WEM2067 is a strong fit for:

  • split-phase residential monitoring
  • single-phase solar systems that need separate grid-side and inverter-side measurement
  • homeowners who want IAMMETER-Cloud visibility without moving up to a larger three-phase meter
  • Home Assistant, Node-RED, OpenHAB, or custom EMS users who want local protocol access

Key Specs

  • Dual-phase meter with 2 measurement channels
  • Input voltage: 80V to 277VAC phase voltage, 140V to 480VAC line voltage
  • CTs: 2 x 150A split-core CTs included
  • Accuracy: voltage, current, and active power rated at +/-1.0%; active energy Class 1 per IEC62053-21
  • Reporting interval: 1 to 5 minutes, typically 1 minute
  • Size: 90 x 36.5 x 58 mm, 2-DIN width
  • Interfaces: Wi-Fi, RS485, Modbus TCP, Modbus RTU, local monitoring options
  • Typical power consumption: <=2W at 230VAC input

Things To Watch

  • This is not the right choice when the project truly needs full three-phase measurement.
  • The product is centered on 2.4 GHz Wi-Fi networking, so network planning still matters in crowded electrical rooms.
  • Its strongest value is in split-phase or two-line residential monitoring, not in large commercial submetering.

Source Notes

This device entry was prepared from IAMMETER's official WEM2067 product page, the WEM2067 datasheet, and IAMMETER's April 18, 2026 launch announcement. Those official sources position WEM2067 as a new dual-phase meter for split-phase homes and single-phase solar import/export monitoring, with pre-order pricing announced at USD 75 and regular pricing expected at USD 88 during launch.
